IPC: H04M9/08
Filed: 1983-12-28
Abstract: PURPOSE:To eliminate the necessity to manual volume adjustment by providing a noise detecting device and a volume adjusting device inside of a telephone set and thereby adjusting automatically the volume of incoming sound and other alarm sound according to the volume of noise in the circumference of a telephone set. CONSTITUTION:A data processing circuit 2 does not send out signal to a controlling line 12 which dial information such as incoming signal, holding signal etc. is not supplied from a circuit 10 to the body 1 of a telephone set. An amplifier circuit 8 of the noise detecting device 4 acts as an ordinary amplifier circuit when a signal is not supplied from the controlling line. When sound noise level is high such as surrounding noise etc. made by amplifying electric conversion signal of sound picked up by a microphone 7 and outputted to a signal line 11, output level to the signal line is also raised. However, the degree of amplification is determined according to the output level. As oscillation sound is not sent from a sound circuit 3 to the volume adjusting circuit 5 when incoming or holding is not possible, no voice is heard from a speaker 6.
